Application October 27, 1943, Serial No. 507,848 z claims. (c1. 12s-17o) This invention relates to a basket grate for stoves.

An object of the invention is the construction of a comparatively simple and eicient basket grate which obviates the use of stove linings, and at the same time produces a far better structure than a lined stove, because of greater heat radiation created by a stove in which my invention is used.

Another object of the invention is the construction `of a basket grate that is efficient, comparatively inexpensive to manufacture, and which can be easily placed in a stove body, and manipulated when in position.

With the foregoing and other objects in View, my invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, Villustrated in the accompanying drawing, and more particularly pointed out in the appended claims.

In the drawing:

Figure l is -a vertical central, sectional View of my basket grate shown in a stove body.

Figure 2 is a horizontal, sectional view taken on line 2 2, Figure 1, and looking in the direction of the arrows.

Figure 3 is a horizontal sectional View taken on line 3 3, Figure 1, and looking in the direction of the arrows.-

Figure 4. is a vertical sectional View taken on line 4 4, Figure 1.

Figure 5 is a fragmentary sectional View of the slotted basket and the grate, showing the peculiar manner or method of placing the grate in position upon the slotted basket.

Figure 6 -is a view in elevation of the grate showing one end of its housing and the spur thereof.

Referring to the drawing by numerals, I designates a stove of any preferred construction; the stove I is provided with a continuous horizontal annular flange 2 for supporting my basket grate.

The basket grate comprises a slotted basket 3 which is provided upon its upper annular rim 4 with a plurality of outwardly extending hori zontal lugs 5. When the basket grate is in the stove I these lugs 5 rest upon the top of the annular flange 2, thereby spacing the basket 3 from the inner walls of the stove I. The basket grate 3 is provided on its lower end with an inwardly extending continuous annular flange 6. This flange 6 is provided on its inner edge with an inwardly extending bevelled face I for the purpose hereinafter described.

The grate 8 comprises a flat body 9 having an integral broad depending housing IU. This housing extends substantially the entire width of the body 9 and is provided at both ends with vertical bearing faces II; each bearing face II is curved to conform to the curvature of the face I of flange 6. These bearing faces Il are adapted to slidably engage the continuous annular flange 6 of the basket 3. On one end of housing I0 and below its curved bearing II (Fig. 6) is a tapering spur I2. Spur I2 is normally under the continuous annular flange 6, to assist in holding the grate in position upon the basket. The broad elongated housing I0 has at one end, opposite to spur I2, a broad socket I3 for receiving the broad inner end of shaker I4. The shaker I4 is broader at I5 than socket I3 whereby the shaker when inserted at its inner end into socket I3, has portions of the broad part I5 engagingthe socketed end of housing I0, Fig. 3.

When inserting the grate 8 into position upon the basket 3, the grate is placed down in the basket in the manner illustrated in Figure 5. BY reason of the bevelled inner edge 'I of riange 5 the spur I2 is permittedv to pass by and under the ange Ii which it would otherwise be impossible to do if the flange 6 was not bevelled in this novel manner. Further, the spacing of the spur I2 below the curved bearing II on housing I0 gives suflicient room for the spur to be under flange 6 and the flat body 9 to be above said flange. When the spur I2 has been positioned under .iiange 6, the ap body 9 will be resting upon the annular flange 6, whereupon the broad inner end of shaker I4 can be inserted in socket I3, resulting in the grate being locked upon the basket against displacement. 'Ihe grate can be easily shaken by swinging the shaker I4, resulting in the grate being rotated upon the flange 6 of the basket 3.

It is to be noted that the spur I2 is bevelled downwardly at I 2a upon its upper face and is not bevelled upon its lower face I2b, thereby making more clearance for allowing insertion of the spur under flange 6, as will be seen upon rst studying Figure 5 and then Figure l. y

Itis to be noted that the greater portion of the slotted basket does not touch the re bowl, which prevents burning of the bowl and also saves the cost of stove linings. Further, through the slotted basket the stove radiates a steady toasting heat that is not obtainable with a lining packed with fine ashes. By using my invention extra heat is gained as the entire body of the stoves gives great radiation, which is not true of a stove that has a lining. Ashes fall freely through the slots of the tions or changes as shall fairly fall within the scope of the appended claims.

What I claim is: 1. In a device of the class described, the combination of a basket provided at its lower edge with a continuous inwardly directed solid annular ilange, said ange being inwardly and upwardly inclined or bevelled on its inner face, a

grate resting on said solid annular flange, said grate being provided with a spur spaced below the upper surfaces of the grate, said spur having 20 its top downwardly and outwardly bevelled, whereby said spur can slide along said bevelled portion of said flange and be positioned under said flange, and a shaker on said grate and coacting with the under-side of said continuous annular flange to hold the grate in position on said flange.

2. In a device of the class described, the combination of a basket provided at its lower edge with a continuous inwardly directed solid annular flange, said flange being inwardly and upwardly inclined or bevelled at its inner face, a grate resting on said solid annular ange, said grate being provided with a depending housing, said housing having Vertical bearing faces on its ends, said bearing faces conforming to the curvature of the annular flange and its bevelled portion, said housing having a bevelled spur spaced below the bearing faces and a shaker-receiving socket on its ends below said vertical bearing faces, said bevelled spur being adapted to slide along and under said bevelled portion of Said annular flange and be positioned thereby under said flange, and a shaker in said shaker-receiving socket cooperating with the underside of said annular flange to hold the grate in position on said ange.
